Description

LIQUID SUPPLIER The present invention relates to a liquid dispenser, in particular liquid soaps, body shampoo, shampoo, disinfectants or the like comprising an assembly and a container. Liquid jets are known such as liquid soap or similar liquids. In pumps used in washrooms or washbasins, often a pump is operated by means of a wrench or lever using pressure or traction, which pump emits some liquid from a container. In such dispensers the pump is fixed in a non-removable manner to the housing, considering that the container is interchangeable. As a result, such a spout can be used only for a liquid since otherwise the pump would have to be continuously cleaned, furthermore it is disadvantageous that the pump remaining in the spout is clogged or damaged and, since such types of clogging can serve as bacterial culture media, hygienic requirements are often not met. Frequent and complicated cleaning of the dispenser is inevitable. CH-A-57 625 describes a dispenser for pasty liquids comprising a container and an assembly for the container. On its underside, the containers are provided with a dispensing opening that is sealable by a valve. To supply a quantity of the content of the container, the container can be compressed anywhere.

CH-A-682 068 discloses a spout in which the container is pivotably supported on a wall surface by a suction cup. In EP-A-0 530 789 a dispenser is suggested which includes a dispensing device which is fixed to the container and is exchanged together with the container. To mount the container, a C-shaped support element mountable to the wall is suggested in which the container is held with its upper end and its lower end. For this purpose, a helmet-shaped lid element is screwed at its lower end onto the discharge device, which element is in turn hooked by a separate support sleeve. This separate sleeve is fastened to the support element by means of an integrated theft protection. The protection against theft can be unlocked with a unlocking pin that can be introduced from the outside. The two arms of the C-shaped support element extend further from the wall than a clamped cylindrical container that can be encompassed and compressed by hand. When the container is compressed, the deformation of the wall of the container is translated in an opening movement of the discharge device. As the wall of the container is compressed, the U-shaped support arch mounted in the container is deformed so that the locking means connected thereto are deflected and the outlet opening is cleared. The liquid to be supplied flows out of the container until the relaxation of the wall of the container leads to the closure of the outlet opening through the locking means. The spout described in EP-A-0 530 789 is disadvantageous in that the Exact doses can only be insufficiently measured As soon as the outlet opening of the discharge device is cleared when the container wall is compressed, the liquid starts to flow out of the container at different speeds depending on its viscosity. This draining does not stop while the container is compressed. Furthermore, this dispenser is disadvantageous due to its complex structure and space consumption. The dispenser is made up of a multitude of individual parts that have to be manufactured separately and also prolong the assembly time Since the arms of the support element have to be long enough to cover the container, the arms extend relatively far into the space. In addition, a separate unlocking pin is necessary for unlocking In contrast, it is an object of the present invention to provide a dispenser that allows simple and effective dosing of different amounts of any viscous liquid., a dispenser will be provided which is comprised of a smaller number of individual gears and whose production and assembly is simple and inexpensive. Preferably such a dispenser saves space and comprises locking means. This object is achieved by the features of the claims. The solution The problem of the present invention is based on the following main ideas. The spout container according to the present invention comprises a front side, two side surfaces, a back side as well as a bottom side. The front side is designed as a manual resting surface that extends from the lower front side to the upper rear side. The two lateral surfaces are designed as elastic and curved clamping surfaces. These different sides are designed and adapted to each other so that dosing can be achieved by simply compressing the side surfaces and simultaneously touching the front side with one hand. The assortment principle will be explained below. The assorted quantity can be regulated by a strong or deep compression differently from the clamping surfaces. In particular, the dose can be predetermined by a correspondingly geometric design of the clamping surfaces. If a clamping surface is printed, a corresponding excess pressure is generated within the container, the pressure of which is compensated in that the self-closing assortment device discharges the liquid until the excess pressure is released. The dispensing device closes as soon as a certain relation between the pressure inside and the pressure outside the container is reached. Therefore, the magnitude of the excess pressure determines the quantity of the liquid dispensed out of the container. Depending on the impression on the clamping surface , a certain amount of the liquid flows out. If the excess pressure is released, there is no effluent even if the clamping surface is printed constantly. If, subsequently, the pressure on the clamping surface is released, its curves contribute to its return to its initial position while the spout device opens again and sucks air into the container to compensate for the partial vacuum that is now shape. Preferably, the seal described for example in EP-A-0545678 and comprising a self-closing valve can be used for this dispensing device. With respect to its opening and closing properties, the valve is selected so that it is adapted to the desired dose taking into account the viscosity of the contents. Therefore, the quantity of liquid to be supplied can be arbitrarily dosed and, and that the effluvium depends on the excess pressure generated by the compression, there is no danger of a voluminous or even complete or even automatic emptying. The use of the self-closing valve known from EP-A-0 545678 results in the following advantageous properties. The valve opens when the first excess pressure is generated in the container and remains open even if the temperature drops and closes again only if a second pressure is reached, which is less than the first excess pressure. In other words, the valve is it is opened by a certain pressure increase and closed by a certain pressure decrease. In this mode, the clamping surfaces are designed so that they can be compressed until the pressure increase necessary to open the valve is reached. In addition, the restoring force of the elastic clamping surfaces is selected such that the pressure decrease necessary to close the valve is effected when the clamping surfaces are released. The dose in this connection is effected as a function of time, that is to say while the clamping surfaces are compressed, the contents of the container are filled. If the clamping surfaces are no longer compressed, the effluvium stops. On its side confronting a wall, the container of the dispenser according to the invention comprises as the first integrated holding device that is removably engageable with first receiving means provided in the assembly of the dispenser. Therefore, the container is mounted only in one location of the assembly, which allows a simple exchange capacity. Since, due to this type of assembly, there is no space between the container and the assembly, the dispenser according to the invention is particularly space-saving. To reduce the individual parts required for the spout, the assembly only consists of two parts, the wall plate and the lid element. The wall plate is fixed to the wall and comprises the first receiving means mentioned above, the lid element serves as a case for the wall plate. The wall plate comprises an essentially arched support arm and second adjacent substantially horizontal receiving means. By means of this arcuate shape, a space is provided which leaves sufficient space for manual collection of the liquid. For this purpose, the container also exhibits an arched shape. By assembling across the reverse side of the container, a support surface long enough for compression of the container is provided in the container. The dispensing device is changed together with the container and, therefore, hygienic requirements are met. Also, cleaning is not needed. In accordance with a specific embodiment, the support arm has an essentially U-shaped profile, thereby providing sufficient space for the integrated locking means. The latter can be placed not visible in the assembly and therefore serve as a protection against theft. For simplicity, the locking means are designed so that the container is released or unlocked by means of lever system by means of pressure from outside on the support arm. For this purpose, the locking means consist of a locking portion and a unclamping portion. By applying pressure to the unclamping portion, the locking portion moves away from the container so that the connection is locked between the locking portion and the locking portion. container is released The arrangement of the locking means completely inside the assembly and its actuation by means of pressure from the outside makes a separate additional unlocking device, such as a pin, superfluous and prevent the working means from being visible from the outside. Furthermore, the locking connection is designed in such a way that both support bags of the support means, with which the working portion is coupled, and the working portion exhibit projections. If someone attempts to remove the upper part of the container without activating the theft protection, the two overlying projections will interfere and thus prevent the locking means from slipping unintentionally out of the support bags of the support means. The invention will now be explained in detail with reference to the drawings, in which Fig. 1 is a side view of a preferred embodiment of a container comprising a dispensing device; Fig. 2 is a rear view of the container of Fig. 1, Fig. 3 is a front view of the container of Fig. 1 held in the assembly, Fig. 4 is a side view of the container of Fig. section of the assembly, Fig 5 is an exploded view of the assembly and the locking means of Fig 4; Fig. 6 is a top view of the device of Fig. 4 with a partial sectional view of the assembly in the area of the support bags, Fig. 6a is a selective elongation of the partial sectional view of Fig. 6; Fig. 7a is a top view of the assembly of Fig. 4; Fig. 7b is a further top view of the assembly of Fig. 4, illustrating the operation of the unlocking mechanism of the locking means; Fig. 8 is a side view of the container of Fig. 1 comprising a cross-sectional view of a further preferred embodiment of the assembly; Fig. 9 is a side view of the embodiment of Fig. 8; Fig. 10a is a bottom view of the embodiment of Fig. 8; Y Fig. 10b is a cross-sectional view of the embodiment of Fig. 8 along line A-B, whose container is formed by the dotted line. Fig. 4 illustrates a side view of a jet with a sectional view of assembly 2 to show the locking means 24 also mounted therein. As shown in Figs. 1 to 4, the container 1 has a specific shape characterized in that the side walls are not perpendicular or parallel to the mounting wall although its front portion is inclined in an arched form from the bottom to the top towards the wall. Since the liquid contained in the elastic container is for tapering by applying the pressure, its cross section is adapted to the shape of a hand holding it, as is evident from Fig. 6, to allow the simple application of pressure In the lower end of the container, the dispensing device 17 is mounted, for example, in the form of a self-closing valve. The last form together with the container 1 a refillable unit that can be exchanged as a whole. The valve can be closed or secured with an alteration-proof seal 16 which can be removed by a predetermined breaking point and thus releases the valve opening. In the side wall 14 facing the wall, the first support means 143 for assembling in the assembly 2 are located and exhibits, for example, a molded cross-section (see Fig. 6a). As a counterpart, the assembly 2 is provided with a slot 211 as first receiving means whose slot is adapted to the shape of the first receiving means 143 and within which the container is pushed vertically so that it is detachably supported. container, it can simply be removed from assembly 2 with an upward movement after the release of the locking means, which will be described below and replaced by a full container. The time for a necessary exchange can be determined by means of the indicator level 18 which is located in a lower front portion of the container and therefore clearly visible Next, the design of the assembly 2 will be explained in detail as shown in Fig 5. Assembly 2 consists of two parts of wall plate 21 and a cover element 23 The important components of the wall plate 21, which is properly mounted to the wall, are the first aforementioned receiving means 211 in the form of a groove and the projecting support arm 22. The support arm 22 is essentially composed of two sections, an arcuate portion 222 and second, adjacent, essentially horizontal receiving means 221. Preferably , the dispenser comprises an assembly of such shape and, in a lower portion, the shape of the container 1 is adapted to this support arm 22. If the container 1 is completely inserted along the slot 211 inside the wall plate 21, its lower portion 142 rests on the support arm 22, the spout 17 then rests on the second receiving means 221 The shape of the latter is suitably adapted The lower portion 142 bears on the arched portion 222. The latter preferably exhibits a U-shaped profile which is essentially open towards the top and is therefore covered by the container nte 1 and forms a cavity The shape of the support arm 22 provides a space between the wall and the valve in favor of which a recessed hand can be held under the valve to collect the liquid without difficulties Therefore, the spout can be operated only with one hand by holding the hand under the valve so that the liquid can be collected to simultaneously compress the clamping surface on it. However, it is also possible to simply hold the hand under the valve while the other hand holds the container 1 on a support surface 11 and compresses it into the holding surfaces 121, 131. The lid 23 is provided as a cover for the wall plate 21. The lid 23 is closed in a lower portion 231 and an upper portion 232. Between those portions 231, 232, an opening 233 is provided which engages the slot 211 and completes the slot as a direct counterpart of the first receiving means 143 in the container 1. Furthermore, the projections 235 are evident from Fig. 6a. In the area of the opening 233, they are parallel to the groove 211 and press the first support means 143 by means of the elastic rear side 14 of the container 1 against the molded inclination of the groove 211 which does not release. To mount the lid element 23 to the wall plate 21, the lid element 23 is first displaced with the opening 233 crosswise on sun second receiving means 221, rotated in the area of the support arm portion 222 towards the perpendicular and, finally, coupled with the wall plate 21 by means of the circumferential jump adjustment connection 234 so that it is held by the latter. The container is then moved into the slot 211 beyond the bottom until the valve rests on the receiving means 221 and the U-shaped support arm portion 222 is covered. Then, the container is in its final position. As mentioned before, the support surface 11 has a specific shape and is inclined towards the top toward the wall. Preferably, it is provided with resilient holding surfaces 121, 131 which face laterally to one another as contact points for compressing the container 1, whose clamping surfaces are curved in order to effect the restoration of the walls of the container after compression. In the front portion of the container, the support surface 11 exhibits a width f of approximately 10 to 50 mm, preferably 37 mm, in the rear portion the width g is approximately 40 to 100 mm, preferably 62 mm. The width f is preferably 25 mm longer than the width g. The support surface 11 shown in Fig. 3 is also used to label the container 1, preferably with an adhesive label 19. The position and length of this label determine the visible portion of the level indicator 18 and therefore the visible residual amount of container contents. Subsequently, the design and construction and mode of operation of the working means 24 will be discussed in greater detail. As shown in Fig. 5, the locking means 24 consist of the locking portion 241 and the unlatching portion 245. The locking means 24 are placed perpendicularly on the wall plate 21 and held by the latter at points A and B. The locking means are mounted on one side to the wall plate by means of a jump adjustment connection at the lower end of the locking portion and on the other side by means of a support support within the supporting arm 22 at point B The actual locking is effected by means of an additional locking connecting element 243 at the upper end of the locking portion 241, whose locking connecting element fits within the supporting bags 144 of the first supporting means 143 on introducing the container 1 into the slot 21 1 of the assembly For this purpose, the working portion 241 is in a section designated as spring element 244 which extends in advance The connecting element 243 to the support bag 144. The unlocking portion 245 of the locking means 24 essentially consists of a preferably round cylindrical section 246. The latter is connected to the working portion 241 by means of a thin wedge-like location. 247 and has a diameter such that it fits within the arms of the U-shaped portion 222, as shown in Figure 7a. If the supporting arm portion 222 is compressed in the direction of the arrow in the area of the Unlocking portion as shown in Fig 7b, this compression effects an extension of the cylindrical portion in the direction of the axis. Due to this movement, in turn, the working portion 241 rotates about a point in the area of the spring element 244 approximately at an angle to the connection. between the locking means 241 and the container 1 is released and the container can be removed upwards Figures 8, 9, 10a and 10b illustrate a spout with an alternative embodiment of the assembly 2 In detail the assembly 2 consists of a wall plate 27 and a lid member 25 The wall plate 27 is provided with mounting holes 271 and 273 positioned in the area of the upper and lower end of the wall plate, respectively, further, an opening 272 is provided in the area of the third top of the wall plate. The cover element 25 is held at the upper or lower end of the wall plate 27 by the jump adjustment connections 252 or 254, respectively. In comparison to the above-described embodiment, the locking means 26 is an integral part of the lid element 25. A lower portion 251 of the lid element 25 extends from the underside of the front upper part and the ends approximately at the height of half of the wall assembly At the upper end, a step is provided on which the lower side of the inserted container 1 rests. A middle section in the area of the upper end is designed as a spring element 264. As is evident in particular from FIG. 9, this spring element 264 is compressible in the direction F towards the wall assembly. Starting from this spring element, a release portion 265 extends inwardly and subsequently toward a locking portion 261 extends toward the upper portion. A reinforcing portion 266 having retainer faces 267 and 268 are connected to the portion. unlatched 265 The upper end of this reinforcing portion is provided with a locking connecting element 263 which is engaged with the support bags 144 in the container when the middle portion 264 is compressed, the upper face 267 is pressed towards the projection 275 as a lid detent. In this way, the lock is released and the container can be removed upwards. During compression, the locking connection element 263 is pressed into the recess area 272 in the wall plate 27. Due to its inherent elasticity the middle portion recovers its initial position and, if a new container is inserted, the insert element locking engagement 263 fits within the respective support bags 144. If someone tries to pull the container 1 out of its assembly without unlocking it, the retainer face 268 will be destroyed from the bottom against the projection 275 and therefore prevents generation of deformation tensile forces on the lid element 25. In other aspects for design and construction and mode of operation, it may refer to the above description of the first embodiment. The second embodiment is advantageous in that its working means do not require an additional component.
